Perpendicular bisector cuts line segment at 90-degree angle. Midpoint found using [(x1+x2)/2,(y1+y2)/2] formula. Slope calculated as (y2-y1)/(x2-x1)
Linear equation describes unique line passing through two points. Equations can be in standard form (Ax + By + C = 0) or slope-intercept form (y = ax + b). Three-dimensional space requires additional vector equation
Slope measures the steepness and direction of a line in the coordinate plane. Slope is calculated as the ratio of vertical change to horizontal change. Slope formula: m = tan θ = (y2 - y1)/(x2 - x1)
A straight line is a two-dimensional entity extending to infinity. The equation of a straight line is y = mx + c, where m is slope and c is y-intercept. The x-axis has a slope of 0, while the slope of parallel lines to the y-axis is undefined
Slope intercept form is used to find equation of a straight line. Formula: y = mx + b, where m is slope and b is y-intercept. Equation must satisfy coordinates of points on line
Slope describes direction of a line on a plane. Represented by letter m, calculated as rise/run ratio between points. Vertical lines have undefined slope
